To aZZ whom it may concern: I I i Be it know'nthat I, ALQIS WoLFMi'ILLfnma citizen of the Kingdom of Bavaria, and a resi- 2, 5 ,tion.

dent'of Munich, Ba-varia, Germany, have invented certain new and useful Improvements n Velocipedes, of which the following is'a specification.

The present invention relates tobicycles of that class which are driven by. motors.

The objecto'f the invention is to produce a bicycle of simple construction audeconomical to manufacture, one that will not easily get out of order nor be easily injured, one in which there is no danger from the motor, and to produce a simple form of motor cheaply operated and easily regulated. a

Figure 1 shows a profile view, and Fig. 2 a

sectional view, of my bicycle. Figs. 3 and 4 show details of the valve-gear, the valve chest, and the lighting apparatus. Figs. 1, J 6, and? illustrate details of 'construc- The driving motor is located'in a fixed structure, which consists of two angular parallel and connected frames made of eight tubes a to a The cylinder is locatedalmost horizontally between the driving-wheel Y B and the steering-wheel A. The steering mechanism oi. the wheel A is the same as in all bicycles. The driving-wheel is spokeless (a disk-wheel) and carries cranks. at both ,that the replacing of the water is only seldom required. The water is conveyed from the reservoir 0 to the chambers d d by the tube a; and returned to the reservoir from the chambers by the tube y, both of which are shown in dotted lines, Fig. 1. I

.The valve-gear operates as follows: The

semicircular am e of the driving-wheel presses upon the rod m at each turn of the wheel through the roller r, and the said rod-"- m is coupled to one end of a pivoted level-f, Fig. 4. The lever f swings on the pivot oandthereby, when the rod m moves backward, the shouldered lever t will move in the opt c site direction. This shouldered lever tearries in the middle of its length a core-piece n, pivoted on the bolt 2', which is pressed down hard upon the lever 25 bythe spring p.

The object is to offer #a certain 'resistanceto the revolving of the core-piece. Thus, forin stance, if the rod m is driven forward and the lever t backward, the part s of the corepiece 'nwill move against the shoulder q and will remainthere stationary. Then the entire core-piece 71- must turn around the bolt 2',

whereby the piece u of the core-piece n will make a motion against the spring .8 and will compress the same. When the lever t goes forward, the part s will not be in contact with q, and as the core-piece 01. turns harder. when the spring S offers its resistance the core-piece 'n. will remain in the same position relatively to the lever 15; but'the entire lever tend its corepiece 20. will be thrown to the other side by the spring S. It now the levert moves back for the second time, the same thing will be repeated, but on the other side at 35g], and S. In its movements the levert catches alternately the angular. levers V or W, which actuate the exit-valves V V and also the ignition-valves V and V. In the backward motion of thepistons of a twin'motor, one drives out the combnstion gases and .the other compresses the mixture, a ndthe various functions of the exitvalve of one of the cylinders and of the ignition-valve could be combined in another cylinder. During the compression period the fuse-valvemust be closed in order to prevent premature lighting. it opens at the dead? point of the interior piston mechanism, while the educt-valv'e of the other "cylinder closes. The fuse-valves are two sided,and in order to secure a sure closing atthe twovalve-seats they are flexibly connected with the anglelevers W W by steel wires'Z Z. ,Thefunc tion of the educt valves is in no way hindered by this arrangement.

V and V are automatically-working.mix-

ture-sucking-in valves; as those used inother gas-motors.

. As will be seen from Figs. 3ahd 4, the priming is a glow-tube priming' The small glowtubes E 'Eare heated bya benzine blow-lamp of the following construction: The required combustible material is conveyed to the wickholder D of the lamp from the reservoir K, Fig.1. The vapor generated in the former passes through the opening I into the Bunsen burner L. I providea conical closing-needle X in thesmallexit-opening, andthis is never obstructed, as experiments have proved. Air is conveyed to the lamp through the caps M and through the frame-tube a in order to avoid the construction of a separate air-couducting tube. This air flows. into the lamps through a short' connecting-tube 2, which branches oif from the air-conducting tube and frame-tube a (See Fig. 2.) As will be seen, the combustible gases pass from the'Bunsen burner L into the glow-tube space lined with fire-bricks y, then into the chimney N, which extends up to the caps M through the tube a". Thus theair'inletas wellastheair-outletpipes terminate in the caps M. In order to make :5-

the lamps burn well, a rather long chimney o. is provided. Besides, as the wheel is submitted to vertical oscillations during the ride, the air in the tubes must be forced to follow perfectly these movements in order that the burning of the lamps continue to be regular. This has been obtained by taking in the inletairat the same height as the mouth of the chimney. Twoequalhighair-columnsarethuscreated, whereby an irregular motion of the combustible air during the riding is impossible. On account of the whirling movements during squalls the inlet and outlet openings cannot be constructed far apart, and therefore they are placed near each other by means of the cap M, the outlet-openings j being constructed around said cap next to the inletopenings 3'. A valve t9, actuated by a chain c and a regulating apparatus arranged upon the handle-bar, Figs- 5, fl, and 7 details, conveys the mixture through apipe to the valvechest. The regulating apparatus consists of a screw s which is movable in a wall-hook s, fixed to the handle-lever. A movable pressing-lever 42", provided with a half-female thread, is pressed by a spring against the screw 8 and holds the latter in position.

One extremity of the screw is connected with the valve t by a chain, which exercises a con stant pressure on the said valve. If the screw is loosened by pressing the lever e down more or less quickly or by pulling it back more or less quickly, the valve for the mixture will opcrate accordingly through the chain and under the influence of the spring, and thereby the motor will act with more or less power and the gait will be increased or decreased. In order to be ableto regulate the motion precisely, the screw sis provided with a divisionrod guided upon the wallhook, and the latter is provided with a scale a, by the aid of which the screw, and consequently the valve t", can

be precisely put in thedesired position. This In order that the motor shall work with more power upon the driving-wheel, a backmotion device in the shape of a spiral spring a: is provided with aconnecting cord or band, and thus the cranks are given a driving motion as well during the forward as'during the backward motion of the pistons. This cord (shown at 20, Fig. 1, in dotted lines) is connected with the piston-rod and tends to draw a the same forward, thus giving the drive-wheel an impulse while the piston is returning to normal position.

The drawing power of the spiral spriugac can be regulated by the nut Z and the small hand-wheel B.
